IMPROVEMENT IN THE MANUFACTURE OF HORSESHOE-BLANKS.

Specification forming part of Letters Patent N o. l2,732, datedSeptember 26, 1876; application. filed March 6, 1876.

To all whom it may concern:

Be it known that 1, J OHN R. WILLIAMS, of Portsmouth, in the county ofScioto and State of Ohio, have invented certain new and usefulImprovements in the Manufacture of Blanks for Horseshoes, of which thefollowing is a specification:

My invention consists, first, in forming calked blanks for horseshoes byrolling, in the manner hereinafter described. The invention furtherconsists in a calked blank for horse shoes, constructed by rolling, ashereinafter described.

In the accompanying drawing, Figure 1 is a front elevation of theadjacent parts of a pair of rolls adapted to carry out my invention.Fig. 2 is a transverse section of the same on the line 2 2, Fig. 1. Fig.3 is a transverse section of the blank previous to its last pass, on theline 3 3, Fig. 2. Fig. 4 is a transverse section of the completed blankon the line 4 4, Fig. 2. Fig. 5 is a transverse section illustrating amodification especially adapted to large and heavy shoes. Fig. 6 is anelevation of the completed blank.

A B represent a pair of rolls, which, in practice. are geared together,so as to rotate in unison in customary manner. The said rolls areconstructed with grooves, substantially as shown at cl efg 71., adaptedby successive passes to produce the calked blank shown in Fig. 6.

The bar comes from the groove 61 with an approximately-rectangularsection, which is modified by the groove 6, and still further by thesuccessive grooves f and g, so that it acquires the section shown inFig. 3 with an angular ridge, 0, out of which the calks c are to beformed, and a convexity at i, which insures the complete filling out ofthe rectangular upper corner in passing through the last groove h. Thefinal groove 71, by means of pockets h and intervening prominences hproduces on the bar the desired number of calks c c, and wider ridgesc", which form the toe-calks of the finished shoe.

The rolls may have a circumference and an adequate number of depressionsto run the length of two or more blanks at each revolution, and the barsare, of course, rolled of a length to be out up into any number ofblanks.

The last two or three grooves of the rolls are formed, as shown, betweencollars on the upper roll and depressions in the periphery of the lowerroll, so that the blanks are turned out with little or no fins.

The catch plates are made to bear on two or more collars, jj, of thelower roll, or else, 7

it adapted to single grooves, they are made to fit around the peripheryof the lower roll to a sufficient distance to prevent their droppinginto the pockets 71.

The rolls shown in Fig. 1 are adapted to produce the bar illustrated inFig. 4, which shows so much of the bar as goes to make a complete blank.The modification in the form of grooves necessary to produce the blankfor larger shoes, (illustrated in Fig. 5,) will be readily understood bythe skilled manufacturer.

The blanks-are finally formed into horseshoes by bending them in therequired shape, stamping between dies, which I have described in anotherapplication, and subsequently punching the nail-holes.

I am aware that straight blanks, with calks of various forms, preparedfor bending into the shape of a horseshoe,'have before been made. This,therefore, I do not broadly claim. My rolled bars for the manufacture ofhorseshoes are peculiar, in that they are constructed in continuouslengths with pyramidal projections 0, arranged in sets or series of anydesirable number in each, with longitudinal ridges c" interveningbetween the sets of pyramidal projections, for the purpose of formingthe toe-calk of the finishedshoes, the bar thus formed being adapted tobe cut into blanks, as before described.

Having thus described my invention, the following is what I claim as newand desire to secure by Letters Patent- 1. The rolls A B, constructedand adapted as herein described, for the production of calkedhorseshoe-blanks.

2. The rolled bar, having two or more sets or series of pyramidalprojections, c, and interposed longitudinal ridges c", substantially asherein described, and adapted to be cut up into blanks for horseshoes.
